Three new chromophores based on the triphenylamine (MM, DM, DN) with various novel electron withdrawing anchoring groups have been synthesized for use in dye-sensitized solar cells (DSSCs). The sensitizers were characterized by 1H and 13C NMR, Mass, UV–Vis, and electrochemical analysis. The HOMO and LUMO electron distributions of the sensitizers were calculated using density functional theory on a B3LYP level for geometry optimization. The DSSC device based on DM dye showed the best photovoltaic performance among MM and DN dyes: maximum monochromatic incident photon-to-current conversion efficiency (IPCE) of 98 %, short circuit current (J SC) of 4.58 mA/cm2, open circuit voltage (V OC) of 0.62 V, fill factor (FF) of 0.77, and overall power conversion efficiency (PCE) of 2.01 %. The results reveal that the difference in number and type of anchoring groups of the dyes significantly influence the photovoltaic performance of their DSSCs.
